irCLIP
Quick-irCLIP, cross-linking and inferred immunoprecipitation, was performed according to the previously published protocol (Kaczynski et al. 2019), with minor modifications. Library was prepared using SMARTer smRNA-seq Kit for Illumina (Takara, 635029) according to the manufacturers instructions. The samples were sequenced on an Illumina NovaSeq S1 with 100-bp paired-end reads.
